Any productivity book will do. It doesn’t matter what book you order though, because you probably won’t read it. You can use any random “increase your productivity” book.

Step 2. Look at the productivity book and tell yourself, “If I don’t get X done, I’m going to have to read that productivity book.”

That’s it. Staring at the cover of a productivity book gives you almost as much of a motivational boost as actually reading the book. And if staring at the cover doesn’t work, then tell yourself the punishment for not getting your work done is that you’ll have to read that dang productivity book. Pretty soon you’ll be off and working. :-)
